The CA6140General Turning Machine Reconstructed By Numeric Control

Ordinary lathe is currently one of the most widely used machine tools,its wide range of technical parameters, a wide range of processing, but the complexityand poor levels of automation, low productivity, does not apply to precision and shapes formachining complex parts. NC machining of mechanical machining industry toward aninevitable trend of development of high quality, high precision and high efficiency. Existingconventional lathe NC system to rebuild it on the basis is a low-cost, highly effective way.After Enterprise existing lathe NC system to rebuild, not only satisfy the needs, saving a lotof funds, has created considerable economic benefits.This dissertation design background mainly is the union domestic concrete nationalcondition, the use existing conventional lathe, through the numerical control transformation,causes it to become one highly effective, the multi-purpose numerical control lathe, is onekind stimulates the storage quantity fund the effective way, also is the low cost realizationautomation effective method.This dissertation mainly carried out the following working：1，To the necessity which the numerical control system of the ordinary lathe designs, andthe advantage after transforming has carried on the detailedanalysis2，Taking example for CA6140engine lathe,the scheme of modifying the engine latheinto the economical numerically controlled lathe is introduced.3，Technique on the Design of Mechanical Sets in Reforming of NC Systems forCA6140;4，According to designing the need, turn the knife rest round to the numerical controldevice, automatically, walk into the driver of the electrical machinery, the selecting type towalk into electrical machinery has carried on the detailed analysis.5，After the transformation of machine tools for the installation and debugging, and wastest all processing...
